Answer:
Step-by-step explanation:
I think this is the equation for annual compunt interest
FV = PV(1 + int)^time PV is present value FV is the future value
PV + Interest = FV
FV - PV = Interest
FV - PV
Interest = [3000(1 + 0.03)^30] - 3000
= 3000(1.03)^30 - 3000
= 3000(2.4272) - 3000
= 7281.79 - 3000
= $4282 to the nearest dollar <------------ Fianl Answer
